MARTIN OMARRA, OF KINGSTON, NEW YORK.

BOLTLESS RAIL-FASTENER.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed August 21, 1907. Serial No. 389,586.

To all whom it may concern:

Be it known that I, MARTIN OMARRA, a citizen of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented a new and useful Improvement in Boltless Rail-Fasteners, of which the following is a specification.

This invention is a novel form of rail fastening device the object being to provide an exceedingly cheap, simple and efficient form of fastener which will completely avoid the use of nuts and bolts and also dispense with the useof fish-plates, chairs and similar ap pliancs.

Another object of the invention is to provide a novel form of rail fastener which is particularly adapted for use in connection with metallic ties Another object is to provide a fastener which can be quickly and easily applied and disconnected.

With these various objects in view my invention consists essentially in the employment of abase-plate having a spring clamping plate connected thereto, said base plate being ada ted to rest upon the to surface of the meta cross-tie, and means For bindin' the clampingplate firmly upon the base 0 the rail.

The invention consists also in certain features of construction and novelties of combi-- In the drawings forming a part of this specification:Figure 1 is a sectional elevation showing my improved form of boltless rail fastener applied. Fig. 2 is a top plan Fig. 3 is a section on the line 33 of Fig. 2. Fig. 4 is a view of the base and clamping plate. Fig. 5 is a detail perspective view of the keeper. Fig. 6 is a top plan'view showing a slight n odiiication. Fig. 7 is a longitudinal section on the line -7.7 of Fig. 6. Fig. 8 is a modified form of the combined base and clamping plate. Fig; 9 is the modified form of the keeper.

Referring to the drawin s A indicates an the usual construction of metallic'cross-tie.

In practice I prefer to construct my fastoning device in such a manner that the base plate will perform the function ofa rail-chair and brace, and I therefore construct the base-plates O with the upturned end C, against which the base of the rail bears, as most clearly shown in Fig. 1, and this hearing end or flange is substantially the same width as the metallic rail tie which is usually about eight inches. At the opposite endof the base-plate is formed a depending bend D, thecontinuation of which is. the clamp. The combined base and clamping plates are formed of stout s ring metal,

ing-plate E.

and the depending bend D is a apted to be inserted in a transverse slot D produced in the to of the metal tie and this securely holds t e fastening device firmly in place and prevents any possibility of the rails spreading or cree )ing). Now, when the rail is seated upon t e ase-plate against the end or flange C, a lever is employed to force the clamping plate down upon, the base of the rail asrmost clearl shownin Fig. 1, and in order to hold the c ampingplate in this position, I employ a keeper B" .which is in the form of an open 100 having the inwardly projecting ends F w ich are inserted in the oblique slots B and forced downwardly until they reach the recesses B cut in the sides of the cross-tie, and this keeper being thus securely locked in osition upon the cross-tie, and straddling the clamping-plate, will securely hold said plate in its depressed position, and in that manner securely fastens the rail to the metal tie, and this without the use of belts or nuts and it will be readily under stood that all danger of the rail spreading or creeping is entirely avoided.

In Figs. 6 to 9 I have shown a slightly modified form of. device which is constructed with the View of economizing in metal, and it will be noted that the base plate C is made considerably shorterand is rovided with a downwardly extending lip 2 which enters a transverse slot C produced in the top of the cross-tie. ing plate are exact y the same. The keeper, however is constructed slightly different, bein g provided with outwardly projecting ends F which are adapted to be passed through openings F produced in. the top of the crosstie and leading from these openings F are the longitudinal slots F in which the side members of the keeper slide, when the said keeper is moved u on the clamping plate for the purpose 0 binding said clamping plate to the rail.

A rail fastener constructed as herein shown and described is particularly useful upon curves as all danger of the rail spreading or creeping is avoided.

Having thus fully described my invention,

Thede ending bend and clampwhat I claim as-new and desire to secure by Letters Patent is:

1. The combination with a railroad rail, of a base plate provided with means to pre-v vent lateral movement of the rail thereon, a clam ing plate integral with the base late and a l ieeper embracin said plate an detachably connected Wit the metallic cross tie. y

2. In a device of the kind described, the combination with the slotted cross-tie, of

the base-plate having afiange at one end and a depending bend at the other end, the

clamping plate integral with the base-plate and extending upwardly from the depending bend, and the keeper having its ends shaped for engagement with the slotted cross-tie, the body of said keeper being adapted to straddle the base and clamping plates and hold them in position in conjunction with a rail, all of said paits being constructed and arranged substantially as shown and described.

3. The combination with a rail tie and rail, of a base late adapted to embrace the base of the rail at one end, the opposite endof said base plate being provided with means to prevent lateral movement of the rail, a clamping plate adapted to engage the rail, said clamping plate being held against lateral movement on the tie, and means for engaging the tie and drawing the plates toward the tie substantially as shown and described.
